This is a very simple, but surprisingly handy project box designed by SparkFun. The box comes with three plastic pieces and includes 4 screws. The insert on the end of the box can be CNC milled (or just dremeled out by hand) for connectors, LEDs, switches.
The bottom section of the enclosure has a unique pattern of raised dots. These dots are on a 0.2" grid. Our plastic standoffs fit nicely onto the 0.09" diameter dots. This allows for a large number of standoff configurations. Using our plastic standoffs, you can mount any shaped board into the enclosure. A small amount of super glue or hot glue will make the mounting permanent.
The outer corners of the SFE box also fit a Eurocard sized PCB (100x80mm). This makes the SFE box ideal for enclosing Olimex and other large development boards.
